What do deactivations in neuroimaging mean?

By now, we’re all familiar with the colourful spots and blobs associated with brain imaging. The assumption is often that areas which ‘light up’ are increasingly activated – and are, as such, implicitly more ‘important’ – in the task under study. But researchers using brain imaging techniques know this to be untrue...more

Brain-based evidence for multiple intelligences?

Is there any brain-based evidence for the theory of multiple intelligences? From my viewpoint, the answer seems clear: Yes….and no. (Germans have a nice colloquialism for this in ‘jein’, pronounced yine.)

Human Brain Mapping (HBM) 2011



Human Brain Mapping in Quebec City was an excellent, if not slightly overwhelming, conference which brought together the often discrepant worlds of neuroscience, psychology, psychiatry, physics, engineering, mathematics, and computer science. (Did I miss anyone?) For a first-timer – and someone relatively new to the world of neuroimaging – it was a whirlwind opportunity to try to absorb as much wisdom as…
